A package (1) is configured to store a powdery material (2) which is to be mixed with a solvent to form a medical solution, such as a dialysis solution. The package (1) comprises a filled cavity portion (6a) containing the powdery material (2), optionally separated into groups of different composition, and a tab portion (9) integrally formed with the filled cavity portion (6a) and being swept around the filled cavity portion (6a) so as to define a roll-up package. The tab portion (9) forms a protective barrier that shields the powdery material (2), e.g. by counteracting transport of moisture into and out of the package. The tab portion (9) may also stabilize the package. The roll-up package is compact, and simple to manufacture and handle.

1. A package for storing powdery material which is to be mixed with a solvent to form a medical solution, said package comprising: a filled cavity portion containing the powdery material, anda tab portion integrally formed with the filled cavity portion and being swept around the filled cavity portion so as to define a roll-up package, the tab portion including an empty cavity portion configured to receive the powdery material from the filled cavity portion when the roll-up package is unrolled, wherein the tab portion being swept around the filled cavity portion generates a force sufficient to maintain the powdery material in the filled cavity portion, and wherein the tab portion being unrolled from the filled cavity portion releases the force such that communication between the filled cavity portion and the empty cavity portion may be established. 2. The package of claim 1, wherein the roll-up package is generally cylindrical. 3. The package of claim 1, wherein the tab portion is swept in at least one full turn around the filled cavity portion. 4. The package of claim 1, which defines a sealed cavity that includes the filled cavity portion, and wherein the empty cavity portion is free of powdery material and is located adjacent to the filled cavity portion. 5. The package of claim 4, wherein the sealed cavity is evacuated to a sub-atmospheric pressure. 6. The package of claim 4, further comprising a connector attached to a wall portion of the empty cavity portion for admitting the solvent and enabling mixing of the powdery material with the solvent within the sealed cavity to form the medical solution. 7. The package of claim 4, comprising first and second overlapping sheets of flexible material which are joined to define the sealed cavity. 8. The package of claim 7, wherein the sealed cavity extends from a first cavity end to a second cavity end, the powdery material being arranged in the sealed cavity such that the filled cavity portion is located at the first cavity end and the empty cavity portion extends from the filled cavity portion towards the second cavity end. 9. The package of claim 8, wherein the filled cavity portion comprises a permanent partition which joins the first and second overlapping sheets and is arranged to at least partly locate the powdery material within the filled cavity portion. 10. The package of claim 9, wherein the permanent partition is arranged to extend in a direction from the first cavity end towards the second cavity end so that the filled cavity portion defines two pockets, and wherein a respective set of powdery material is arranged in the two pockets. 11. The package of claim 9, wherein the permanent partition is arranged with a spacing from the first cavity end such that an open pocket is defined between the permanent partition and the first cavity end in the filled cavity portion, and wherein at least part of the powdery material is contained in the open pocket. 12. The package of claim 8, wherein a plurality of sets of powdery material are located in the filled cavity portion side by side from the first cavity end towards the second cavity end, wherein at least two of the sets of powdery material have different hygroscopic properties, and wherein the set of powdery material that is most hygroscopic is located closest to the first cavity end. 13. The package of claim 7, wherein the filled cavity portion and the empty cavity portion are separated by a releasable seal that joins the first and second overlapping sheets. 14. The package of claim 7, wherein the filled cavity portion and the empty cavity portion are separated by a constriction region, in which the first and second overlapping sheets are brought into close proximity with each other without being fixedly attached to each other. 15. The package of claim 14, wherein the first and second overlapping sheets are brought into close proximity with each other in the constriction region at least partly by action of a force generated by the tab portion being swept around the filled cavity portion. 16. The package of claim 1, wherein the filled cavity portion contains at least two sets of powdery material of different compositions and is configured to physically separate the at least two sets of powdery material in the roll-up package. 17. The package of claim 1, wherein the medical solution is one of a dialysis concentrate, a dialysis solution, an infusion solution, a nutrition solution, a replacement solution, and a plasma expander solution. 18. The package of claim 1, wherein the powdery material comprises an acid concentrate powder for preparation of an acid concentrate for use in dialysis. 19. The package of claim 1, which is configured for use in a blood dialysis treatment or a peritoneal dialysis treatment. 20. A package for storing powdery material which is to be mixed with a solvent to form a medical solution, said package comprising: a filled cavity portion containing the powdery material,a tab portion connected to the filled cavity portion, the tab portion sized to wrap around the filled cavity portion at least one time and including an empty cavity portion configured to receive the powdery material from the filled cavity portion when the tab portion is unwrapped from the filled cavity portion, wherein the tab portion being swept around the filled cavity portion generates a force sufficient to maintain the powdery material in the filled cavity portion, and wherein the tab portion being unrolled from the filled cavity portion releases the force such that communication between the filled cavity portion and the empty cavity portion may be established; anda connector attached to the tab portion for admitting the solvent to enable mixing of the powdery material with the solvent to form the medical solution.
